IMPROVED SASH SUPPORTER AND FASTENR.

Specification forming part of Letters Patent-No. 34,304, dated February 4, 1862.

l the sarhe with the interior exposed. Fig. Sis

a vertical section at x..

Similar letters ot' reference indlcate corresponding parts in the several figures.

The invention is especially applicable to the Windows of railway-cars and analogous purposes; anditconsists in a device by which the sash is seciirfed atyfany point at which it is placed, and by the application of the hand toy the proper point' tofraise or lower it is automatically released, scthat it may be freely moved,

To enable others skilled in'the art to make and use my invention, I will proceed to de-- scribe its construction and operation.

A represents the Window-frame; B,' the.

sash. O C are a pair of boltspressed outward by springs D D. The bolts C C are provided at their inner ends with pins or studs lc c, engaging. in oblique slots of any suitable form in a slide E, which slide is provided with Va knob or handle F.

The handle F is intended 'to have such prominence that it constitutes the most ready and evident means by which the window may be raised or lowered. Any person therefore (whether familiarwith the nature of the con trivance vor not) in `applying a hand to the knob to raise or lower the sash retracts the bolts, thus rendering it free to move, and. on the withdrawal of the hand the bolts automatically secure the sash in any position in which it may have been placed.'

A slide an inch square may be placed, in l the center of the lower frame of the sash and connect with rods or bolts extending .through the frame to ratchets-in the grooves in which the sash plays; or it may be placed in any other position where it will accomplish -a similar result.

Having thusdescribedmy inver.- tion, What claim as new, and desire to secure by Letters Thev obiiqueiygrooted' sus@ in the de;

.scribed combination, with bolts C c, springs D, and a knob or handle F, the latter being employedto move the slide E, and ilrewise the sash itself, in either direction, all as hereinbefore explained.
